btrfs: zoned: limit active zones to max_open_zones

Browse source

When there is no active zone limit, we can technically write into any
number of zones at the same time. However, exceeding the max open zones can
degrade performance. To prevent this, set the max_active_zones to
bdev_max_open_zones() if there is no active zone limit.
